Reinforced sealing rings
The present disclosure provides a sealing ring assembly having a sealing ring and a reinforcement, configured to seal a high-pressure region from a lower pressure region of a piston and cylinder device. The sealing ring may be segmented, and a metal layer, wire, or other reinforcement may be affixed to the ring. The reinforcement is placed into tension against the sealing ring, which is correspondingly placed into compression. The composite structure of a relatively brittle sealing ring and reinforcement provides for reduced tensile loads in the sealing ring, thus extending life and reducing the likelihood of failure. The brittle portion of the sealing ring assembly may include a polymer or ceramic such as graphite, which is relatively less strong in tension than compression. |

Transmission mechanism
The disclosure relates to a transmission mechanism with at least two gearwheels that can be brought into form-fitting engagement with one another. One of the gearwheels is designed as a movable gear and, in a disengaged position, is arranged in a freely rotatable manner on a transmission shaft. The other of the gearwheels is designed as a fixed gear and is arranged non-rotatably on a further transmission shaft, the movable gear is connectable non-rotatably to the transmission shaft by a clutch unit and at least one transmission gear can be engaged if a clutch toothing of the clutch unit engages in a form-fitting manner in a toothing of the movable gear in a tooth-on-tooth-gap position. A sensor device detects a rotational speed signal incoming into the other transmission shaft and a rotational speed signal outgoing from the transmission shaft. |

Shift device that enables detection accuracy to be improved
In a shift device, a shift position of a knob is altered as a result of a knob being rotated. Furthermore, a Hall IC on a wiring substrate detects a rotation position of a magnet in the knob, thereby enabling the shift position of the knob to be detected. Here, the Hall IC is placed on an outer side in a rotation radial direction of the magnet. Because of this, it is possible to enlarge the change in the relative position between the magnet and the Hall IC that is generated by the rotation of the magnet, thereby enabling the detection accuracy when detecting the shift position of the knob to be improved. |
